Progress: More than twenty projects were funded that were specific to this objective. Scientific advances in this area include mechanistic and mutation linkages of epilepsy and ASD-like behaviors, as well as circadian rhythm disruptions downstream of ASD-associated mutations.

Remaining Gaps, Needs and Opportunities: While studies on co-occurring conditions have been initiated, a greater depth of understanding is needed. Further efforts are needed, especially on wandering, metabolic and immune conditions related to ASD, as well as a systems-biology approach to understand how these co-occurring conditions are related to ASD. In order to more accurately assess progress, wandering/elopement should be considered separately from seizures/epilepsy/sleep. Familial autoimmune disorders could be moved to 2.S.A to be grouped with other immune-related issues.
